Consolidation of Cu-based amorphous alloy powders by high-pressure torsion

We applied high-pressure torsion (HPT) for consolidation of gas-atomized metallic glass Cu 54 Zr 22 Ti 18 Ni 6 powders into high-density bulk disks. The effects of the number of revolutions ( N  = 1–5 turns), applied pressure (2.5–10 GPa), and temperature (298–473 K) on densification and structural...
